Seasonal effects of wind conditions on migration patterns of soaring American white pelican. [PDF]

PLoS One, 2017
Energy and time expenditures are determinants of bird migration strategies. Soaring birds have developed migration strategies to minimize these costs, optimizing the use of all the available resources to facilitate their displacement. We analysed the effects of different wind factors (tailwind, turbulence, vertical updrafts) on the migratory flying ...

<i>Eimeria erythrorhynchosi</i> n. sp. (Apicomplexa: Eimeriidae) from the American white pelican <i>Pelecanus erythrorhynchos</i> Gmelin, 1789 (Pelecaniformes: Pelecanidae) in Toluca, Mexico. [PDF]

Int J Parasitol Parasites Wildl, 2023
A new coccidian species, Eimeria erythrorhynchosi n. sp. (Apicomplexa: Eimeriidae) collected from the American white pelican Pelecanus erythrorhynchos Gmelin 1789, is reported from Toluca city, Mexico.

Seasonal Habitat Selection by American White Pelicans

Diversity, 2022
Resource utilization strategies of avian migrants are a major concern for conservation and management. Understanding seasonal habitat selection by migratory birds helps us explain the ongoing continental declines of migratory bird populations. Our objective was to compare the second-order and third-order habitat selection by the American White Pelican (

Linking Isotopes and Panmixia: High Within-Colony Variation in Feather δ2H, δ13C, and δ15N across the Range of the American White Pelican. [PDF]

PLoS One, 2016
Complete panmixia across the entire range of a species is a relatively rare phenomenon; however, this pattern may be found in species that have limited philopatry and frequent dispersal. American white pelicans (Pelecanus erythrorhyncos) provide a unique

Influenza A viruses in American White Pelican (Pelecanus erythrorhynchos). [PDF]

J Wildl Dis, 2010
The role of many wild waterbird species in the ecology and epidemiology of avian influenza viruses (AIV) remains unclear. We report the first isolation of AIV from American White Pelicans (Pelecanus erythrorhynchos; Pelecaniformes) in North America. Two H13N9 AIVs were isolated from hatchling birds in breeding colonies in Minnesota, USA, during 2007 ...

West Nile virus in American White Pelican chicks: transmission, immunity, and survival. [PDF]

Am J Trop Med Hyg, 2013
West Nile virus (WNV) causes significant mortality of American White Pelican chicks at northern plains colonies. We tested oropharyngeal/cloacal swabs from moribund chicks for shed WNV. Such shedding could enable chick-to-chick transmission and help explain why WNV spreads rapidly in colonies. WNV was detected on swabs from 11% of chicks in 2006 and 52%

Influence of Climate Change on Productivity of American White Pelicans, Pelecanus erythrorhynchos [PDF]

PLoS ONE, 2014
In the past decade, severe weather and West Nile virus were major causes of chick mortality at American white pelican (Pelecanus erythrorhynchos) colonies in the northern plains of North America. At one of these colonies, Chase Lake National Wildlife Refuge in North Dakota, spring arrival by pelicans has advanced approximately 16 days over a period of ...

Surveillance for West Nile Virus in American White Pelicans, Montana, USA, 2006–2007

Emerging Infectious Diseases, 2010
West Nile virus (WNV)-associated deaths of American white pelican (Pelecanus erythrorhynchos) chicks have been recognized at various nesting colonies in the United States since 2002. We evaluated American white pelican nesting colonies in Sheridan County, Montana, USA, for an association between WNV-positive pelican carcasses and human West Nile ...

Large- and Small-Scale Climate Influences Spring Migration Departure Probability of American White Pelicans

Diversity, 2022
Endogenous (e.g., age and sex) and exogenous (e.g., climate and resource availability) factors influence avian migration phenology. However, little is known regarding the migration ecology of birds at the non-breeding grounds, including the American ...

Migratory Movements and Home Ranges of Geographically Distinct Wintering Populations of a Soaring Bird

Diversity, 2022
Migratory soaring birds exhibit spatiotemporal variation in their circannual movements. Nevertheless, it remains uncertain how different winter environments affect the circannual movement patterns of migratory soaring birds.
